' FLUID PUMB Filed July 14. 1921 ATTORNEY Patented Aug. 7, 1 923.,

GUSTAVO A. SAUCE-II, O13 PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO "WESTINGHOUSE ELECTRIC AND FLUID Application filed July 14,

To aZZ whom it may concern:

Be it known that l, t-iusmvo A. Sitcom, a. citizen of the United. States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented anew and useful lniproven'ient in Fluid Pumps, of which the following is a speciflcm tion.

This invention-relates to fluid pumps or blowers and more particularly to pumps employing a volute casing, and has for an object to provide apparatus of the character designated which shall be compact, rugged in construction, durable in operation and in which the driving and driven pump elements form a unit and are mounted within the pump casing.

The above and other objects will be more manifest from the following specification and drawings in which Fig. 1 is a. view in elevation of an apparatus embodying my invention, and Fig. 2 is a view in section thereof, taken on the line IIIl oi 1.

The invention contemplates a fluid pump or blower having a volute casing in which the central portion is arranged to accommodate a. motive power device for pumping a fluid through the pump. The central portion, hereinafter, for convenience termed the motor casing, is supported by hollow vanes or struts which may serve to allow motive fluid to be supplied or discharged from the power device located within the casing. The internal structure is arranged to coop erate with the inlet passages to form smoothly curved fluid inlet passages to the interior of the pump.

Referring to Figs. 1 and 2 of the drawing for a more detailed description of an apparatus embodying my invention, 1 indicate at 10 a blower casing, preferably of the volute type and formed in. symmetrical. halves 24 and 25 joined by lugs 2323. The casing has provided therein opposed inlet openings 11 and 12 and a discharge opening 13. The dischargeportion 13 has integrally formed therewith a flange l-il having openings 15 provided therein by which suitable fastening means may be inserted to rigidly mount the blower in any desired position. The blower casing 10 is provided with a hollow central casing portion 16 which is supported in place by suitably arranged hollow strut members 17 which may serve as directing vanes for the fluid being IVIANUFAGTURING COMPANY, A CORPORATION OF PENNSYLVANIA;

drawn into the blower. The vanes 17 are made hollow to provide passages to the inner casing which may serve to supply motive fluid as from a pipe 26 to a suitable power apparatus 18 located therein. As indicated a steam turbine 18 ol the impulse type is rectly connected to a shaft 19. The shaft is mounted in suitable bearings 20 and carries propellers 21 and 22 which operate in the respective inlet openings 12 and 11. Steam or other motive fluid is admitted through the struts of the member to suitable nozzles 25 26 directed at the turbine wheel 18 and is discharged through the struts of the member 2 1- to an exhaust pipe 2'7. The casing member 16 is designed to cooperate with the casing inlet passages to enable large quantities of fluid to be handled by the blower.

The motor pump set above described may be assembled by securing together the two symmetrical casing members to form the pump casing and mounting therein the moving part 18.

The present invention enables the building oi a. pump that may be utilized as a blower to supply compressed fluid and air to fur- .naces and bulkhead compartments where it is desirable to deliver any quantity of fluid and air at constant or varying pressures. The compactness of the pump makes it desirable :tor installations where a separate blower and motor could not be operated advantageously. By arranging the symmetrical pump and motor casing to be cast integrally, the cost of manufacture is greatly reduced.

While T have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptiblcof various other changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

Vl hat I claim is:-

1. A pump oil the character designator comprising a pump chamber, a motor casing within the pump chamber, and one or more hollow guide vanes extending between the pump chamber and the motor casing, said vane or vanes being adapted to communicate with the interior of the motor casing.

2. A pump casing having inlet and dieill) charge means, a hollow fluid-directing member between the inlet and discharge means, guide vanes supporting the fluid-directing member within the pump casing, and conduits provided in the guide vanes for communicating with the hollow fluiddirecting member.

3. A pump having a casing provided with inlet and discharge means, a hollow fluiddirecting member between the inlet and the discharge means, guide vanes supporting the fluid directing member within the pump casing, driving and driven pump elements car ried by the fluid-directing member, and means provided in the vanes to supply motive power to the driving pump elements.

4. A volute pump of the character designated comprising a pump chamber, a motor casing within the pump chamber, and hollow guide vanes formed integrally with the pump chamber and motor casing, said vanes being adapted to communicate with the interior of the motor casing.

5. A pump casing having inlet and discharge means, a hollow fluid-directing member axially alined between two inlet means, guide vanes supporting the fluid directing member and formed integrally with the pump casing, and conduits provided in the guide vanes for communicating with the hollow fluid-directing member.

6. A fluid pump of the propeller type having inlet and discharge means, a hollow fluid-directing member axially alined betweentwo inlet means, guide vanes supporting the fluid directing member integrally with the pump casing, the driving and driven pump elements being carried by the fluid-directing member and means provided in the vanes to supply motive power to the driving pump elements.

7. A fluid pump of the propeller type having inlet and discharge means, a hollow fluid-directing member axially alined between two inlet means, guide vanes supporting the fluid member integrally with the pump casing, oppositely disposed propellers carried by the fluid-directing members and operating within the inlet means, a motor located within the fluid directing means, and means provided in the vanes for supplying motive power to the motor driving the pump elements.

In testimony whereof, I have hereunto subscribed my name this 9th day of July,

GUSTAVO A. SACCI-II.
